## 📃 Overview


📚 **EPIC-Bench** is a **Mask-Grounding-based** benchmark designed to evaluate a VLM’s **Visual Perception** capability in **Embodied Scenarios**. EPIC-Bench covers **3 High-Level Categories** and **23 Task Types**, following the realistic **Embodied Workflow**:

- 🎯 **TargetLocalization**: **Pinpoint** the right object in the scene from a natural-language instruction.
- 🧭 **Navigation**: **Approach** the target step by step by reading key visual cues along the way.
- 🤲 **Manipulation**: **Operate** on the target through fine-grained, action-oriented **Grounded Perception**.

</p>

The goal is to measure whether models can reliably perceive the critical **Visual** information required throughout the **Embodied Process**.
